Performance of entanglement purification including maximally entangled mixed states
Juan Mauricio Torres, József Zsolt Bernád, Rocío Gómez-Rosas
Entanglement between distant quantum systems is a critical resource for implementing quantum communication. This property is affected by external agents and can be restored by empl…
Optimal two-qubit gates in recurrence protocols of entanglement purification
Francesco Preti, Tommaso Calarco, Juan Mauricio Torres +1
We propose and investigate a method to optimize recurrence entanglement purification protocols. The approach is based on a numerical search in the whole set of SU(4) matrices with…
Onset of universality in the dynamical mixing of a pure state
M. Carrera-Núñez, A. M. Martínez-Argüello, J. M. Torres +1
We study the time dynamics of random density matrices generated by evolving the same pure state using a Gaussian orthogonal ensemble (GOE) of Hamiltonians. We show that the spectra…
Entangling operations in nonlinear two-atom Tavis-Cummings models
Rocío Gómez-Rosas, Carlos A. González-Gutiérrez, Juan Mauricio Torres
We derive an analytical approximate solution of the time-dependent state vector in terms of material Bell states and coherent states of the field for a generalized two-atom Tavis-C…
Breakdown signatures of the phenomenological Lindblad master equation in the strong optomechanical coupling regime
Ralf Betzholz, Bruno G. Taketani, Juan Mauricio Torres
The Lindblad form of the master equation has proven to be one of the most convenient ways to describe the impact of an environment interacting with a quantum system of interest. Fo…
Atomic Bell measurement via two-photon interactions
Carlos A. González-Gutiérrez, Juan Mauricio Torres
We introduce a complete Bell measurement on atomic qubits based on two photon interactions with optical cavities and discrimination of coherent states of light. The dynamical syste…
